Routing USB through FPGA

Hi, I'm having some difficulties routing USB through my DE-1 FPGA board. The goal is to make the FPGA chip look like a bare wire to an USB throughput. The thought was to have it perform the han...

No, Im just new to LVDS signals and wanted to route the complete differential signal into my FPGA chip and out again. Having some minimal routine (clock -> buffer) pass along the entire signal. As tho it where a piece of wire.

I have a cyclone 5 so it has the 2.5V LVDS. And a nice fractional crystal oscillator @72Mhz.

But if I understand correctly, the thing you are suggesting is that my design needs bidirectional differential signals in order to work? Or minimally to spoof some outgoing signal to a computer?

I will take a look at FTDI phy chips, but the spoofing part is important. And want to consider part1 first.
